Some insight on UCSF: they are only interviewing 30 people this year out of 325 applicants. I asked for one of my end-of-interview questions "what does UCSF want in a competitive applicant." Here was the director's response: applicant shows they are very committed to getting into medical school, already has volunteer experience with under-served communities, motivated to succeed, wants to work with under-served communities in the future.
Questions asked:
A few point blank ones (did you take class A, class B, do research, want to work in ___ communities)
Standard interview questions overall, but they definitely put a spin on their questions. Greatest strength, weakness, what you can contribute to the cohort, why medicine, and expect to explain everything on your app!
